T0 a/ZZ/ whom it may concern:

Be it known that I, JOSEPH C. IIosnoR, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented an Improvement in Loading Devices for Conveyors, of whichthe following is a specification.

Heretofore the buckets of conveyers have been filled progressively froma chute by means of a series ot' hoppers moving along with the bucketsand at the same time covering the intervening spaces between the con-Voyer-buckets to prevent spilling. It is frequently desirable toprogressively deliver different materials at a point of destination, sothat the materials mix as delivered, and it is also desirable toregulate or control the proportions or quantities of the differentinaterials; and the object of my present invention is to eiect theseresults.

In carrjing out my invention and in coinbination with conveyor ofgravity-buckets and chains i employ a series or range of covering-platesmoving along Wit-h the buckets and operated thereby and whichcoveringplates are provided with openings at diit'erent points, and aseries oi hoppers with projecting chutes are so placed as to tome in.line with the ditionu .topeningr; in the series of plates to deliver irerial troni the hoppers and chutes into oilli'erent buckets when theopenings in the pates taiineiile with the mouths-ot" the chutes, thematerials beingeut oit as the impertorate plates or portions' thereofpass beneath the chutes.

In the drawings, Figure l is alongitudinal section and partial ele ationillustrating my improvement, and Fig' .l a partial cross-sectifn'i andelevation at .or et Fig. l.

The gra n, the links o, torni.- ing endle,V ;hain.'s,with rollers ifbetween the links ot the chain, and the tr; same are of any ordinary orwel lfig. L is a partial plan view, i

c. l'or the Y. i-ltnown f construction I'lir the puipose of conveying;

at the pivots of the links, the said rollers contacting` with andbearing upon the rollers Z1' of the eonveyer-buckets, the said endlesschains surrounding and being supported by the said shafts and wheels ce', and the chains being provided between the links and rollers withplates 2, that project and which come between the links h and contactwith the respective ends of the intermediate links b, so

that by the movement of the conveyer and buckets the endless chains faremoved along with the conveyer or" buckets and around the Wheels e e inthe direction of the arrow shown in Fig. l.

Between the endless chainsfI place a series of cove ing-plates g, withabutting.,r parallel edges, the ends of said plates being secured to therespective links forming the endless chainsf, so that said endlesschains are connected by said series of plates, which formcovering-plates when in their lower position above the gra viiy-buclietsand the spaces between the buckets. As a preferable manner of securingthe ends of the plates 5,/ to the links of the chains f I prefer toemploy angle-irons, one portion of each of which is riveted to thechains and the other portion of each angle-iron to the plates. This willbe apparent, especially by reference to Fig. 3, although Ido not limitmyself to this form of structure.

llacii alternating covering-plate j is provided with a rectangularopening 3, and these openings are made in diiterent parts of the plates,the longer portion ot' the opening bcing transversely ot the plate, andwhen said.

openings coincide with adjacent buckets, as shown in l'lig. il, theintermediate coveringplates extend over the openings between thegramty-buckets, and l proviile a series oi hoppers /t and chutes /t'extending therefrom, the hoppers being outside the vertical plane of theendless ciiainsj', se that materials may be delivered into the lioppers,and the chutes extend from the hopper.; downward. and between the upperand lower levels of the covering-plates, the said chutes varying inlength and having open ends adaptefl'to come above the reetangiil rcitings in the covering;- plates. l\'i-f A4tud. i) specially illustratethis consti' ne the right-hand chute of Fig. 2 is the shortest, theleft-hand chute the longest, and the intermediate chute of a .lengthbetween the right IlO ` of the chute and is adapted to prevent theIloWof material from the chute except when one of the rectangularopenings comes below the chute, at which time the material flows fromthechute through the perforation into the gravity-bucket, and astheseries of covering-plates move along the flow of material is cuto untilanother opening comes beneath the chute. This Operation is similar forall the chutes.

It 'will be apparent from this construction not only that the variousgravity-buckets can befilled by differentl materials, but also that anyone bucket is only filled with one material. It is, however, obviousthat the openings. may be so placed that several successive buckets maybe iilled from one hopper with the same material or that the differentmaterials from theA several hoppers may bedelivered alternately andprogressively in the gravity-buckets; also, that as the material isdelivered at the desired place the various materials follow one anotherin rotation and mix las delivered, and the proportions of the materialsto be delivered may be varied as desired by filling one or more bucketsin or der with the same material before the following buckets are filledwith other material.

My invention is specially useful in connection with blast-furnaces Wherethe same are charged with predetermined quantitiesof different materialsin progression, so that when the furnace is lighted the charge isproperly mixed tol produce the desired degree of heat and com positionfor properly fluxing and inciting the ore. It is also apparent that theinvention is applicable for Vmixing other ma`V 'serials-such, forinstance, as different kinds of coal-for for the mixing of coal and coke,s

or for the mixing of dierent substances of chemical operations.

I claim as my invention- 1. The combination with a conveyer ofgravity-buckets and chains, of a series of covering-plates moving alongwith the buckets, alternate plates having perforations at differentpoints, and hoppers and chutes for materials to be delivered placedwith! the mouths of the chutes in line with the vaiious moving openingsof the coverin g-plates, substantially as set forth.

2. The combination withthegravity-'buckets, chains,` rollers and trackforming a conveyer, of endless chains, supports therefor and aroundwhich the chains'move, a series ot plates connected to and extendingacross between the said chainsand covering the gravity-buckets and thespaces between the same, means'for moving the said series ofcovering-plates and their chains with and by the conveyer, there beingperforations in al.

ternate plates of the series at different points and hoppers and chutesfor receiving materials so placed as to deliver the materials throughthe openings of theplates into the buckets, the material being cut offin the hop-v pers bythe imperforate portions of the plates,substantially as set forth.

3. The combination With the devices forining a conveyer of'gravity-buckets, of devices for feeding different materials todifferent buckets of the conveyer, devices moving with and bytheconveyer, and interposed between the buckets of the conveyer and thedevices for delivering material, and adapted to simnltaneously deliverdifferent materials into different buckets and to cut oil' the materialfrom intervening buckets, substantially as set forth.

Signed by me this 16th day of August, 1900.
